Thank you everyone

for supporting me. Truly, I depend on your input and suggestions
I agree that CPS will have to talk to the little girl, though she didnt mention to my daughter who the boy was. I guess they have ways of talking to children so they feel comfortable enough to reveal what happened and who the other child is.
I am guessing that I dont have to call CPS since my friend (their teacher) is going to call Family Services and get them involved. She said that is what she legally has to do and she knows people there anyway.
Would I call CPS even though my friend is getting Family Services involved? Or should I wait to see what happens with this and if they talk to the little girl?
